      CPU and System Topology

      Server Description

      A budget-friendly, burstable ARM64 virtual machine with four cores and low memory for lightweight, intermittent workloads.

      Burstable & BudgetGeneral Purpose

      Microsoft Azure B4pls_v2 is a burstable virtual machine from the Bpsv2 family, built on the ARM64 architecture using an Ampere Neoverse-N1 processor. Operating under the Microsoft Hyper-V hypervisor, it provides 4 physical cores (4 vCPUs) at 3.0 GHz and 8.0 GB of RAM, resulting in a low-memory profile of 2.0 GB per core. The instance includes no local storage or GPUs but supports premium storage. Performance benchmarks place this server in the entry-level tier, with average stress-ng CPU scores but weak Geekbench and PassMark memory results. Its burstable CPU allocation offers qualitative cost efficiency for intermittent workloads, making it a budget-friendly choice. The B4pls_v2 is suited for lightweight database operations, basic web serving, and development environments that do not require sustained high-performance compute.

      Workload Profiles

      0.32Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
